<p>The means exists for virtual code applications to have run time error
messages written to standard error on their behalf by
<code>avram</code>. Any error messages not documented here originate with an
application and should be documented by it.
</p>
<p>Most error messages originating from <code>avram</code> are prefaced by the
application name (i.e., the name of the file containing the virtual
machine code), but will be prefaced by <code>avram:</code> if the error is
caused by a problem loading this file itself. Error messages originating
from virtual code applications are the responsibility of their
respective authors and might not be prefaced by the application name.
</p>
<p>The run time errors not specifically raised by the application can be
classified as internal errors, i/o errors, overflow errors, file
format errors, application programming errors, and configuration related
errors.
</p>
<p>Some error messages include a code number. The number identifies
the specific point in the source code where the condition was
detected, for the benefit of the person maintaining it.
